Problem: Knowing How Networks and Devices will Behave Under Real-World Conditions
Effective testing requires a real-world environment that reproduces realistic network conditions and behavior. All software and hardware should be subjected to a realistic test environment before deployment.
What is Network Emulation and Impairment
Real production networks experience delay and network impairments that are not normally duplicated in lab test environments. These lab test setups are normally very controlled pristine networks and do not reflect reality.
Network Emulation simulates real-world conditions such as delay, drop, traffic shaping, and other impairments. These impairments are added to the traffic mix to produce the required conditions. The emulation device is transparent to the network and is placed inline allowing bi-directional impairment.
Why Testing Without Network Impairment is INVALID
By emulating realistic and worst-case network conditions in the lab, users can validate and test performance of new hardware, protocols, and applications to prevent failures in production networks. Testing without network impairments and delay is invalid and does not properly provide the real-world test environment needed for complete testing.
